The posting

At DIGITALL we dont just deliver technology we deliver the future! We are explorers, knowledge-hunters, tech geeks, problem solvers and game changers who want to inspire and be inspired. Our DIGITALL people are always one step forward: working with top-notch technologies, creating innovations ahead of the market trends, sharing the passion for discovering better ways. As a human-centric organization, our teams are built on mutual respect and open communication, allowing everyone to be authentic, express ideas and unleash their potential. We are proud of our DIGITALL bright minds and never stop developing their skills to keep pushing boundaries together and do what we love. DIGITALL operates globally with a team of 1000 experts in 16 locations across 8 countries.

We are seeking a backend developer responsible for designing, building and maintaining TypeScript/Node.js services that support a training platform.

This is your job:

  • Design, develop and maintain backend services using TypeScript, Node.js (NestJS) and PostgreSQL.
  • Work within CI/CD pipelines (Jenkins) and containerized/orchestrated environments (Docker, Kubernetes).
  • Collaborate with cross-functional team members on architecture, code reviews and technical refinements.

In addition, all team members share the following standing responsibilities under the RFP's Service Scope:

  • Be online, accessible and responsive during core working hours, 08:00–17:00 CET/CEST.
  • Actively participate in technical and non-technical team discussions, sprint ceremonies and planning.
  • Produce high-quality code following agreed within team conventions (naming, folder structure, formatting, security).
  • Maintain test coverage above 80% (unit, integration, API and E2E tests) for all new functionality, including edge cases such as rollback.
  • Raise pull requests for every feature and address review comments through the release tool.
  • Fulfil the team's Definition of Done for every backlog item before closure.
  • Rotate through the Supporter of the Sprint duty (and its backup) — triage and resolve incidents/bugs/questions raised during the sprint, maintain PBIs with meaningful status updates, and hand over cleanly to the next supporter.
  • Participate in the on-call rotation where assigned after 6th month — be reachable by phone/SMS within 15 minutes and ready to work within 30 minutes, including weekend refresh windows; document incidents (timeline, actions, resolution, next steps).
  • Maintain up-to-date technical and process documentation (e.g., Confluence) for any breaking change, new API, or architectural update.
  • Keep ticket status current at least every other day while work is in progress.
  • Communicate proactively: flag blockers early, report absences/out-of-office in the calendar, and collaborate across teams and disciplines (T-shaped skills encouraged).
  • Rotate through the Supporter of the Sprint duty (and its backup) — triage and resolve incidents/bugs/questions raised during the sprint, maintain PBIs with meaningful status updates, and hand over cleanly to the next supporter.
  • Maintain up-to-date technical and process documentation (e.g., Confluence) for any breaking change, new API, or architectural update.
  • Keep ticket status current at least every other day while work is in progress.
  • Communicate proactively: flag blockers early, report absences/out-of-office in the calendar, and collaborate across teams and disciplines (T-shaped skills encouraged).

Your qualifications:

  • Proven working experience in TypeScript with Node.js (NestJS) and PostgreSQL.
  • Working experience with GitHub (push/pull/merge workflows), Jenkins, Docker and Kubernetes.
  • Experience operating in large-scale datacenter/cloud/network environments.
  • Bachelor's or Master's degree in Computer Science, Physics, Mathematics or a related technical/science field.

Preferred / Nice to Have

  • Experience with Dynatrace, PowerShell or similar tooling.

General Requirements

  • Bulgaria; available for on-site meetings in Sofia at least every second week.
  • Fluent in English and Bulgarian.
  • Experience with public cloud providers, preferably GCP (AWS/Azure also acceptable).
  • Minimum ~8 years of relevant experience, commensurate with the assigned seniority level.
  • Agile mindset — comfortable working in a trust-based, empowered, continuously-learning Scrum environment.

All applications will be treated in strict confidentiality.

Please note that only shortlisted candidates will be invited to an interview.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
